To all whom it may concern:

Be it known that I, ROBERT E. MANLEY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Presses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a press which is especially adaptable for use in automobile repair shops and garages. The essential object in view is the provision of a press of exceedingly simple and cheap, though strong construction, both as regards the framework of the press and the operating. parts, which press is rapid in action when operating on light work and is capable of developing exceedingly heavy pressures when operating on heavy work.

lVith the above and other objects in view, the invention consists in certain constructions, arrangements and combinations ofparts here'nafter described in a preferred form and particularly pointed out in the claims at the end of the specification.

In the drawings,-

Figure 1 is a front elevation of a press constructed 'in accordance with the present improvements.

Fig. 2 is a vertical sectional elevation of the same on the line 22 of Fig. 1.

Fig. 3 is a top plan view of the press.

Fig. 4 is a horizontal section through the upper frame taken in a plane indicated by the line 44 of Fig. 1.

Fig. 5 is a horizontal section through the lower frame taken in a plane indicated by the line 55 of Fig. 1.

Fig. 6 is a detail vertical sectional elevation of the screw and its operating parts, on the line 6 6 of Fig. 3.

Fig. 7 is a detail vertical sectional elevation on the line 77 of Fig. 4, illustrating the mode of operating the screw when used for developing high pressures in connection with relatively heavy work.

Like characters of reference in the sev- In accordance with the present invention, the .main frame of the press is constructed substantially of bars of commercial cross section. for example, channel bars, such as can readily be purchased in the open market, quickly cut into the proper size, and assembled to produce a frame of great strength, though of minimum cost. The main frame of the press consists essentially of a relatively wide portion, which may be termed the lower frame A, and a relatively narrow upper portion or frame B mounted upon and supported by the lower frame. Said main press frame is constructed in the following manner: The lower frame A consists of spaced lower vertical channel bars 3 and 4 which are mounted on suitable ground supports 1 and 2, and are connected together at their upper ends by spaced horizontal channel bars 55 respectively, secured rigidly to the opposite flanged portions 3 4 of the vertical bars 3, 4. Secured to and positioned between the horizontal bars 5, 5 of the lower frame are upper vertical bars 6, 7, which are, in turn, connected together at their upper ends by horizontal bars 8, 8, secured to the flanged portions 6, 7 of said bars 6, 7. The bars 6, 7 and 8. 8 constitute the upper frame B, and the latter is made considerably narrower than the lower frame by positioning the upper bars '6. 7, some distance between the lower bars 3, 4, as shown more particularly in Fig. 1. That portion of the horizontal bars 5, 5, which is located between the vertical bars 6, 7, constitutes a table C for supporting relatively narrow or small articles to be operated upon by the press mechanism, as will hereinafter appear. In order to adapt the press for use with wider or larger articles than could be accommodated between the bars 6, 7, the

lower frame is provided with a lower table I), preferably mounted so as to be capable of vertical adjustment relatively to the lower frame. The lower table D is constructed of a pair of spaced horizontal channel bars 9, 9 connected together by means of short lateral bars 10, 10 and further braced laterally by angularly extending bars 11. 11, as shown in Fig. 5. The horizontal bars 9, 9 overlap the flanged portions 3, 4: of vertical bars 3, 4, and are supported by laterally-extending pins 12 mounted in holes 13 formed in said flanged portions. Each bar 3, 4, is provided with a vertical series of spaced holes 13, permitting adjustment of the pins 12 to different heights and corresponding adjustment of the lower ta ble D.

As will hereinafter appear, the press is adapted respectively to engage the top and bottom faces of the upper and lower tables. The brace rods 14; extend between the bars 5, 5, 9, 9, and greatly augment the resistance of the bars 9, 9 to heavy strains, such as would be produced when operating the press with the hereinafter described high leverage connections on an object, a wheel or exam supported upon the bars 9, 9. Tn practice, the brace rods 14 are adjusted as near the center of the bars 9, 9, as possible; when operating on a wheel, thismay be fiCCOIH! plished by removing nuts 15 and cross-pieces 17, then removing the rods 14 and positioning the rod between two-01E the spokes and close to the hub of the wheel. After the rods have been thus positioned with their upper ends projecting through between the bars 5, 5, at points intermediate the upright bars 6, 7, the cross pieces 17 can be replaced and the rods again secured to the frame by the nuts 15;.

lit desired, the lower frame A of the main press frame may be rendered additionally secure by angularly-extending bracing rods 19, 19, respectivel connecting the upper ends of the vertical bars 3, 4., with the outer ends of the ound supports 1 2. The lower frame may e further braced by means of a longitudinally extending bracing bar 20 connecting said ground supports and the bars 3, 4, together, is slibwn in Fig. 1.

The improved press mechanism or the present invention will now be described.

Centrally supported between the upper horizontal bars 88 or'the upper frame B is a bearing 20 adapted to receive a vertically disposed screw 21. The screw is provided with an axially extending groove 22 which receives a key 23 supported by the .bearing 20 for the purpose of holding the screw against rotation relatively to the frame, while permitting axial or vertical movement of the screw. The screw constitutes the pressure transmitting member of the press and its lower end is adapted for the attachment of various devices for operating on articles supported upon the press frame, and "for this purpose the lower end oi the screw is provided with a horizontally extending peripheral groove 24 adapted to receive the locking member, for example, a small screw mounted in a device attached to the lower end of the screw 21. most order to brace the lowertable D when menses tically with respect to the main press frame by means of a horizontal nut 27 rotatably mounted on the screw but, held against substantial vertical or axial movement with respect to the main press frame. For the latter purpose the nut is provided with-a sleevelike portion 28, of relatively reduced diameter and formed in said sleeve-like portion is a horizontally extending annular groove 29 which receives a fixed stop or extension 30 of the bearing 20, so, as to prevent longitudinal' movement of the nut 27. Preferably, the annular groove 29 is made somewhat wider than the extension 30, thereby permitting the. nut 27 and screw to yield somewhat vertically. The upper end of the screw 21 is adapted to proyect beyond the horizontal bars 88 of the upper frame, and the loose mounting above described permits a slight vertical movement of the screw. As the upper end of the screw is exposed, a sharp blow applied to the upper end of the screw by hammer or mallet may readily be transmitted by the screw to loosenor dis- 1% lodge parts firmly stuck or frozen to the arleverage system when it is desired to op- 110,

crate the parts in connection with relatively light work, or in cases where the development oi? excessive pressure is unnecessary, (2) or by a high power or relatively slower acting leverage system in cases where it isnecessary to develop the highest pressures possible. Formed on the nut 27 isan annular ring-like portion 31 relatively larger in diameter than the sleeve-like portion 28 of the nut and provided with a horizontally 12c extending annular series of teeth 32, which teeth are cult clear to the periphery of the ring-hire portion, as shown. In order to impart a rotary. movement to the nut 27 when operating the latter according to the first levera e system aboveset forth, there is provide an actuating bar or handle 33 having an arcuate tooth 3d at its inner end, the tooth being adapted to fit in the annular plied so as to occupy a. radial position with respect to the ring-like portion, in the manner shown in the drawings, a back and forth movement of the actuating handle in a substantially horizontal plane will be effective to transmit a relatively rapid axial movement to the screw 21, the handle being held in engagement with the tooth during the forward movement and elevated out of engagement on the return movement. While the action of the press is quite rapid in operating the same by applying the handle in 'this manner. it will be found that a 1000 to 1 leverage may be developed.

The following connections are em loyed in the high power leverage system: ivoted in a suitable vertical bearing 36 supported by the vertical bar 7 of the upper press frame is a bell crank lever 37, the arms 37 and 37 of which are movable in substantially horizontal planes. A reciprocatory operating bar 38 is pivoted to the end of the arm 37 of the bell crank lever, and said operating bar 38 is provided with a slot 39 which receives a fixed guiding and supporting member 40 suspended from one of the horizontal bars 8-8 at the top of the upper frame B. A back and forth movement of the bell crank lever of course imparts a reciprocatory movement to the horizontal bar 38, and the latter motion is utilized to transmit a step-by-ste movement to the actuating nut 27 throug the ring-like portion 31 of the latter. sult, the operating bar 38 is formed with a socket 41 in which is loosely mounted a pawl 42 adapted to engage a tooth 32 of the ring-like portion 31. On forward movement of the operating bar 38, the pawl imparts a one-step movement to the ring-like portion 31 of tie nut 27, and on return movement of sai operating bar 38 the pawl 42 yields upwardly in its socket 41, so as to pass over the next tooth of said ring-like portion. The arm 37 of the bell crank lever is formed with an elongated socket 43 which is adapted for the reception of an actuating handle, such as the handle 33. The end of the handle 33 opposite to the arcuate tooth 34 may be inserted in the socket 43'a-nd the bell crank lever oscillated back and forth, as indicated above, to impart a step-by-step movement to the actuating nut.

In operating the screw 21 in accordance with the last mentioned system of levers, the progression of the screw is relatively slow but enormous ressures can be developed. For examp c, it is quite possible In order to effect this re-.

to obtain a leverage of approximately 2200 to 1. When a high power leverage system is not in use, the pawl 42 may be lifted out of engagement with the teeth 32- and so retained by ositioning a small lateral pin 42? carried y the pawl over a retaining projection 42 formed on the upper face of the operating bar 38, which holds ,the pawl in elevated position. i

i As will be noted, the above described pressis exceedingly simple in construction and operation. The various parts constituting.

the frame may be secured together by any suitable fastening devices, for examp e, ordinary bolts and nuts of proper strength may be employed for securing together the various bars constituting the frame. The utility of the press is furthermore not limited to the employment of the press mechani m above described. For example, the upper table C may be utilized as a work bench-- for any of the numerous uses found in machine shops and garages. I

As shown in Fig. 1, the vertical bars 6,

7, are .secured at top and bottom to the bars 8, 5, by means of detachable fastening devices such as nuts and bolts. By removlng the pair of the bolts from the upper end of one of said bars 6, 7, and one bolt from the lower end thereof, the bar may be swung outwardly onits lower bolt, as a pivot. This permits the insertion of an open frame larger than the upper frame of the press in the space between the bars 6,, 7, for example, when it is desired to operate the press in conjunction with an inner portion of a large frame. If at least one end of the bars 6, 7, were not removable in the above set forth manner, this highly advantageous feature would not be present. After a large. frame has been thus slipped into position forbeing operated on by the press, the displaced bar may be shifted back into positionand again secured by reapplying the bolts. The above operation is repeated when it is desired to remove the frame from the press.
